MILK-BOTTLE TOP.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed February 17, 1919. Serial No. 277,687.

To all whom it may concern:

Be it known that I, MARY M. WILLISTON, a citizen of the United States of America. and resident of I-lolyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Milk-Bottle Tops, of which the following is a full, clear, and exact description.

This invention relates to improvements in closures for milk and cream bottles and its leading object is to provide a closure formed of paper or card board or like material with an overlying fluted portion providing an annular finger hold, to permit of the ready removal of the closure and to prevent dirt from falling into the milk or cream.

Another object of the invention is to pro-- vide a closure which can be made of relatively thin stock and which is shaped to provide a reinforced outer edge which will not easily fracture or swell and which will form a positive sealing fit with the neck of the milk or cream bottle.

With the above and other objects in view the invention consists in certain new and useful constructions, combinations, and arrangements of parts, olearlydescribed in the following specification and fully illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a milk or cream bottle with the upper portion shown in section and the closure also shown in section.

Fig. 2 is a plan view of the closure.

Fig. 3 is an edge view thereof.

Fig. 4 is a transverse sectional view of a modified form.

Referring to the accompanying drawings illustrating the application and construction of my invention, A designates a milk or cream bottle which is provided with the usual neck B which is formed with an internal shoulder C constituting a valve, as in the usual construction.

On the shoulder or valve seat C the seal ing disk 0r valve D is disposed. This sealing disk or valve is formed of paper or other thin flexible material and consists of a base portion D and an overlaying annular flange D integral with the base D and formed by fluting the material in such manner that the flange D is of conical formation, and projects slightly above the plane of the base portion D to permit of the insertion of the point of a finger beneath theflange, so that the disk may be easily grasped and removed. The flange D is folded over the base and provides a folded edge D' for the disk which will not unravel or swell under the action of the milk or cream or moisture. The width of the flange D may be as shown or less or greater than this width. The flange on the disk provides a receptacle for any dirt that may fall onto the disk.

By means of my invention the use of a special implement for removing the disk is rendered unnecessary.

In Fig. 4 I show a slightly modified form of the invention, wherein a thin piece of paper or similar material is employed and a bead E is formed at the point of connection between the base F and the overlying fluted flange G, which provides an air filled sealing edge or rim portion.

Having described my invention I claim:

1. A sealing disk for milk bottles and the like consisting of a circular base portion adapted to seat on the shoulder of a bottle and formed with an overlying fluted flange extending inwardly providing a continuous finger hold for the removal of the disk from the bottle.

2. A sealing disk for milk bottles formed with a base portion adapted to seat on the neck of a milk bottle and an overlying fluted flange connected thereto by a beaded rim-forming portion and extending inwardly of the edge thereof and providing a finger hold for the removal of the disk.

3. A sealing disk for milk bottles consisting of a circular portion adapted to seat on the shoulder of a milk bottle and an annular fluted flange extending inwardly from the edge of the circular portion to provide a continuous normally collapsed finger hold.

4. A sealing element for milk bottles consisting of a disk adapted to seat in the bore of a milk bottle neck and provided with a fluted annular flange extending inwardly thereof to provide a finger hold for the removal of the disk from the bottle neck, the

flange providing a central opening for the hold having a central opening for the inserinsertion of a finger thereunder. tion of a finger.
